The organizers of the Algebraic Graph Theory International Webinar would like to invite you to join us and other colleagues on March 15, 2022, at 7pm Central European Summer Time (= 5pm UTC), for the next presentation delivered by Misha Muzychuk. 

Please note that we have switched to Central European Summer Time which may mean for some of you that the talk has moved to one hour earlier (5pm UTC).

The title of Martin's talk: Generalised dihedral CI-groups

Abstract:
A finite group R is called a CI-group if two Cayley graphs over R are isomorphic iff they are isomorphic by an automorphism of R. It was known that a generalized dihedral group Dih(A) is a CI-group only if A is a direct product of elementary abelian groups of odd order. In my talk a new restriction on the structure of A will be presented, namely: if Dih(A) is a CI-group, then for every odd prime p the Sylow p-subgroup of A has order p, or 9. This is joint work with Edward Dobson and Pablo Spiga.
